Printing Ceramic Pastes on the Sygnis F-NIS and Sygpast – DIW Guide
Print your own ceramic paste — the Sygnis F-NIS 23151 and Sygpast are open DIW platforms for alumina, zirconia, SiC and other pastes you formulate or buy.
- Al₂O₃, YSZ, ZrO₂, SiC, aluminosilicate, TiO₂ and zeolite pastes
- Pneumatic extrusion up to 4 bar, Luer Lock nozzles 0.10–1.50 mm
- Print seals and insulation straight onto a component
- You source the paste and fire the green parts in your own furnace
What your process engineer actually checks
Printable rheology, real fired properties
The paste has to extrude cleanly and hold its shape during printing, then deliver the ceramic's real strengths after debind and sinter — heat resistance, mechanical strength, wear and corrosion resistance and electrical insulation. We tune both the rheology and the firing schedule, and account for shrinkage, so the printed part meets spec.
A materials engineer on the line
Chemistry selection, paste tuning and debind/sinter guidance from engineers who run ceramic AM. Trial prints available.
- Ceramic pastes and slurries — alumina, zirconia, YSZ, silicon carbide, aluminosilicate, titania
- Zeolite pastes, listed by Sygnis among F-NIS materials
- Commercial high-temperature ceramic adhesives and putties, printed as seals
- Pastes whose flow depends on temperature — 10 ml cartridge heated to 60 °C (F-NIS C, D, E)
- Two-component pastes — on the Sygpast with its SLE2 head
- Prints the green part; drying, debinding and sintering happen in your own furnace
Which ceramic pastes the Sygnis printers print
The F-NIS 23151 and the Sygpast are Direct Ink Writing (DIW) printers: air pressure pushes the paste from a syringe cartridge through a Luer Lock nozzle, and the paste’s own rheology holds the bead in shape. Sygnis built the F-NIS to print ceramics, silicones and other one-component pastes, and its user manual names functional ceramics and filters as applications. Sygnis lists silicones, ceramic pastes and zeolite pastes as examples of F-NIS materials.
Because the head moves over the platform without touching the part, the paste can also be laid directly onto an existing component. Sygnis’s application examples are high-temperature gaskets and seals printed from commercially available ceramic adhesives and putties onto alumina, stainless steel, graphite and clay, and Sygnis describes the HydroGEN project, in which it printed insulation for solid-oxide electrochemical cells. The printer delivers the shaped green part; the fired properties come from your paste and your firing schedule.
Ceramic classes in the Sygnis materials list
| Ceramic | Why it is chosen |
| Alumina (Al₂O₃) | high thermal conductivity, electrical insulation, wear and corrosion resistance |
| Yttria-stabilized zirconia (YSZ) | thermal and chemical stability for high-temperature use |
| Silicon carbide (SiC) | very hard, wear-resistant, high thermal conductivity, chemical resistance |
| Zirconia (ZrO₂) | high fracture toughness — structural parts |
| Aluminosilicate (Al₂O₃–SiO₂) | high-temperature stability and thermal shock resistance — refractory use |
| Titania (TiO₂) | high refractive index and dielectric properties — optical and electronic use |
The Sygnis materials overview is in the Downloads tab above, and a short video of ceramic printing is in the Video tab.
Process parameters from the Sygnis documents
| Pressure | up to 4 bar (400 kPa); calibration starts at 0.100 MPa |
| Material flow | 0.5–1.5 ml/min |
| Nozzles | Luer Lock, 0.10–1.50 mm; calibration files use 0.41 mm |
| Resolution | Z 0.1 mm · XY 0.2 mm |
| Cartridges | 30 / 55 ml; 10 ml heated to 60 °C on C, D, E |
| Platform | tempered glass to 120 °C (A, B, C, E); cooled −15 °C to ambient (D) |
| UV | 365 / 405 nm for pastes with a photocurable binder (B and up) |
| Work field | F-NIS 230 × 150 × 150 mm · Sygpast 250 × 250 × 250 mm |
For multi-phase pastes and pastes with solid particles, Sygnis offers Teflon-lined dispensing tips, whose lining is designed to prevent clogging; stainless steel tips suit finer, lower-viscosity work.
Getting a new paste to print
Where the printer stops — and what you bring
The printer does not come with ceramic paste. You source or formulate it, and its firing schedule, shrinkage and fired properties are the paste supplier’s or your own, not Sygnis’s or ours. The F-NIS prints the green part only: drying, debinding and sintering need your own furnace, and the part shrinks when it is fired. The F-NIS prints one-component pastes up to 4 bar; very stiff pastes may need more, and Sygnis has built higher-pressure versions (6, 8 or 10 bar) as custom modifications, quoted case by case. For two-component systems or parts that need supports during printing, take the Sygpast. For silicones see printing silicones on the F-NIS and Sygpast.
